"The Summa Theologica is the best-known work of Italian philosopher, scholar, and Dominican friar SAINT THOMAS AQUINAS (1225 1274), widely considered the Catholic Church s greatest theologian. Famously consulted (immediately after the Bible) on religious questions at the Council of Trent, Aquinas s masterpiece has been considered a summary of official Church philosophy ever since. Aquinas considers approximately 10,000 questions on Church doctrine covering the roles and nature of God, man, and Jesus, then lays out objections to Church teachings and systematically confronts each, using Biblical verses, theologians, and philosophers to bolster his arguments. In Volume I, Aquinas addresses: the existence and perfection of God the justice and mercy of God predestination the cause of evil the union of body and soul free will and fate and much more. This massive work of scholarship, spanning five volumes, addresses just about every possible query or argument that any believer or atheist could have, and remains essential, more than seven hundred years after it was written, for clergy, religious historians, and serious students of Catholic thought."

No collection of philosophy or theology is complete without this classic work of Thomas Aquinas. Designed for study, this edition makes the Summa Theologiae accessible to everyone.

Summa Theologica Part I (Prima Pars) Thomas Aquinas - The Summa Theologiae (Latin: Compendium of Theology or Theological Compendium; also subsequently called the Summa Theologica or simply the Summa, written 1265-1274) is the best-known work of Thomas Aquinas (c.1225-1274), and although unfinished, "one of the classics of the history of philosophy and one of the most influential works of Western literature." It is intended as a manual for beginners in theology and a compendium of all of the main theological teachings of the Church. It presents the reasoning for almost all points of Christian theology in the West. The Summa's topics follow a cycle: the existence of God; Creation, Man; Man's purpose; Christ; the Sacraments; and back to God. (courtesy of wikipedia.com). This is part 1, 'Prima Pars'. Aquinas's greatest work was the Summa, and it is the fullest presentation of his views. He worked on it from the time of Clement IV (after 1265) until the end of his life. When he died, he had reached Question 90 of Part III (on the subject of penance). What was lacking was added afterwards from the fourth book of his commentary on the Sentences of Peter Lombard as a supplementum, which is not found in manuscripts of the thirteenth and fourteenth centuries. The Summa was translated into Greek (apparently by Maximus Planudes around 1327), Armenian, many European languages, and Chinese. It consists of three parts. Part I treats of God, who is the "first cause, himself uncaused" (primum movens immobile) and as such existent only in act (actu) - that is, pure actuality without potentiality, and therefore without corporeality. His essence is actus purus et perfectus. This follows from the fivefold proof for the existence of God; namely, there must be a first mover, unmoved, a first cause in the chain of causes, an absolutely necessary being, an absolutely perfect being, and a rational designer.

A major new study of Aquinas and his central project: the understanding of human nature.

Aquinas on God presents an accessible exploration of Thomas Aquinas' conception of God. Focusing on the Summa theologiae – the work containing Aquinas' most systematic and complete exposition of the Christian doctrine of God – Rudi te Velde acquaints the reader with Aquinas' theological understanding of God and the metaphysical principles and propositions that underlie his project. Aquinas' conception of God is dealt with not as an isolated metaphysical doctrine, but from the perspective of his broad theological view which underlies the scheme of the Summa. Readers interested in Aquinas, historical theology, metaphysics and metaphysical discourse on God in the Christian tradition will find this new contribution to the studies of Aquinas invaluable.
